- 10.3.1 — Presents technical case against 5G NR RM code baseline for small UCI payloads, arguing performance is far from optimal. Proposes studying novel DMRS-less transmission using VHC product-code strategy, claiming up to 3dB SNR gain and 6.6dB PAPR reduction at 1% outage compared to legacy PUCCH Format 3. Argues DMRS overhead up to 28% in PUCCH Format 3 introduces sub-optimality for short block lengths, and that VHC achieves low receiver complexity by separating detection in time and frequency domains.
- 10.6.1.1 — Proposes a product-code based Vertical-Horizontal Coding (VHC) strategy where input bits are encoded independently in frequency-domain (vertical) and time-domain (horizontal), allowing independent decoding to reduce receiver complexity. Proposes studying increased payload capacity (>8 bits) for enhanced grouping or UE-specific wake-up. Presents simulation results showing ~4dB gain at 1% BLER compared to Rel-19 sequence-based design under TDL-C 30ns with 15-bit payload over 11 PRBs, and demonstrates VHC can achieve similar performance to Rel-19 while consuming roughly 3x fewer resources (168 REs vs 528 REs) at the expense of longer transmission time.

Discussion on Channel Coding for Small Block Lengths
EURECOM argues that 5G NR Reed-Muller (RM) codes are suboptimal for small UCI payloads and proposes studying novel DMRS-less transmission schemes using vertical-horizontal coding (VHC) for superior coverage, performance, and PAPR. The…
Discussion on design of WUS with OFDM based sequence
EURECOM proposes a Vertical-Horizontal Coding (VHC) product-code scheme for 6G Wake-Up Signal (WUS) design that separates frequency and time domain encoding to reduce receiver complexity. The document makes 2 Observations and 2 Proposals,…
